[The myosin-activating protein kinases in human myocardium: localization and content].
Using the immunofluorescence approach, we have determined that the recently detected protein kinases, among which are RhoA-activated kinase, integrin-linked kinase, zipper interacting protein kinase, and death-associated protein kinase, which are capable of phosphorylating myosin, are localized in the Z-lines sarcomeres of human myocardium. Additionally, we studied the content of integrin-linked and zipper interacting protein kinases in human embryonic myocardium, as well as in normal and hypertrophic adult human heart. The content of these protein kinases in adult normal myocardium increases in comparison with the embryonic heart. The content of integrin-linked and zipper interacting protein kinases in hypertrophic myocardium is higher compared with the normal adult heart. The data obtained suggest the involvement of these protein kinases in the development and hypertrophy of human heart.
